No, it is not hopeless. One reason is because young people today are searching for meaning and purpose in their lives - and only Jesus Christ is the answer to their search. When they discover this, their lives are changed and they become deeply committed to Him.
Over the years, we have seen this repeatedly in our evangelistic missions. Recently, for example, my son Franklin held a major Festival (as he calls his evangelistic Crusades) in the country of Taiwan. Almost 10,000 people responded to the invitation to commit their lives to Jesus Christ - and almost two-thirds of those were below the age of 25. The same is true almost everywhere we proclaim the Gospel.
Young people today are confronted with all kinds of ideas and temptations, and it's easy for them to be led astray. But this world can never meet the deepest yearnings of their hearts, nor can it promise them lasting hope for the future. But Christ can - because He alone has broken down the barriers between us and God, and He alone teaches us who we are and why we are here. The Bible says, "In him was life, and that life was the light of men" (John 1:4).
Pray for our youth, and pray especially for the young people you know. Then ask God to help you point them to Jesus, who alone is "the way and the truth and the life" (John 14:6).
